If the world erased laws, and concepts such as violence, good and evil, people would see the world is inherently violent. Look at storms, earthquakes, disease, and predators for example, and you will begin to understand concepts such as evil and war are only wrong vis-ŕ-vis the genealogy of language. There is no good or evil apart from the human consciousness, therefore, since no one consciousness has clear and distinct perception, why care at all?
